Mars' Hellas Basin 4 Billion Years Ago - Deepest Place On Mars

Hellas is also the largest well preserved crater on Mars, its outlines are obvious. In this video I take a look what studies have to say with regards to its rich history and with that construct a timeline of what happened to it during its most dynamic period.
